Notes:
The ideal sheet texture for electric motor steels, the λ fiber, with 〈001〉 normal to therolling plane, that can be produced by directional solidification, is largely lost by the required heavyrolling reduction and recrystallization needed to produce thin motor laminations. However by twosuccessive light rolling reductions, followed in each case by recrystallization, the desired texturewas largely recovered. Taylor and finite element modeling supported the hypothesis for thissuccessful processing: the low Taylor factor of the λ fiber grains. Although starting from similargrain sizes, the second light deformation produced a much larger recrystallized grain size than didthe first light deformation. This result suggests that a lower average Taylor factor in the structurebefore deformation, resulting in lower stored energy, can increase the recrystallized grain size
